Hello, everyone.
I have found something strange on my linux mint 14 (32-bit version).
After a sketch, which uses SerialUSB, has been uploaded to Maple Mini and Maple mini finished its re-starting, I tried "screen /dev/ttyACM0" and failed again and again. But after I tried "sudo screen /dev/ttyACM0", it worked. I quit and tried the same command without "sudo", it also worked.
I tried thsi way and that way many times. It seems "sudo" first will alway make things normal. But other operations like restart udev or even restart OS, or restart maple IDE, does NOT help.
Why?
Thanks!
